Roku is exploring ways to show consumers ads on its TVs even when they are not using its streaming platform: The company has been looking into injecting ads into the video feeds of third-party devices connected to its TVs, according to a recent patent filing.
This way, when an owner of a Roku TV takes a short break from playing a game on their Xbox, or streaming something on an Apple TV device connected to the TV set, Roku would use that break to show ads. Roku engineers have even explored ways to figure out what the consumer is doing with their TV-connected device in order to display relevant advertising.
I still have an "air mouse keyboard combo". Used a dongle to transmit but worked great. One side had arrow buttons, 2 buttos for clicking, I wiggled my wrist to point the cursor, and a keyboard sat on the back. I think I paid like $10 for it. Went from stick pc to Amazon due to specs vs price. Considering migrating back though.
There's also phone apps that do the job and they just hook up via wifi.
